Is swine fever airborne?

With the outbreak of classical swine fever, many farmers have received certain economic losses, and most of them do not know much about classical swine fever. What are the modes of transmission of classical swine fever? Is classical swine fever airborne?

Is classical swine fever airborne?

Classical swine fever can be transmitted through the air, mainly through the mouth and upper respiratory system into the pig body, in the nasopharynx or tonsil infection, the virus quickly spread to the mandibular lymph nodes, through lymph and blood throughout the body.

1. Insect-borne transmission, African classical swine fever virus can be transmitted by ticks, mosquitoes, mosquitoes, chelate flies and so on, and African classical swine fever virus can reproduce in individual insects and remain active for a long time.

two。 Infected domestic pigs and wild boars can be transmitted through fresh meat products, blood and semen, and can survive for up to 4-6 years under certain conditions, as well as through bacon, ham, and infected pig faeces.

3. In addition, feed contaminated by virus, blood feed, hogwash, water sources, appliances, clothing worn by farm staff, and air pollution near the farm are all potential sources of infection after the outbreak of the epidemic.

Second, what if classical swine fever occurs?

After the outbreak of an epidemic in the farm, if the farmers do not report the epidemic, and if the enclosure has not been strictly disinfected, it may cause the nearby farm to spread through the air. We must pay attention to this point, heighten our vigilance and do a good job of prevention.

According to the notice of the Ministry of Rural Agriculture of 24 January 2019 on the issuance of a new version of the Emergency implementation Plan for Classical Swine Fever epidemic in Africa, it is pointed out that the most effective disinfection products are 10% benzene and phenol, hypochlorite, strong alkali and glutaraldehyde. It is very important to firmly select appropriate disinfection products for the prevention and control of African classical swine fever. Huisheng biological product "system", active ingredients: glutaraldehyde 5%, decylmethylammonium bromide 5%, high-efficiency disinfectant, after strict evaluation and identification, it is effective for blue ear disease virus, porcine epidemic diarrhea virus, African classical swine fever virus and so on. The above drugs can not only kill the virus on the ground and appliances, but also kill the virus in the air, which is safe and reliable.

In the current situation, if it is an open trial farm, the safety is still not guaranteed, we can use bamboo poles, rattan frames, plastic sheeting and so on to close, which is more conducive to disinfection and avoid the invasion of foreign viruses. In order to avoid the deterioration of the air quality in the farm, the exhaust device can be installed, the air inlet should be filtered as much as possible, the disinfection should be changed frequently, and the air quality should be kept fresh as much as possible.

As there is no effective treatment vaccine for African classical swine fever virus at present, it is mainly based on prevention. After the outbreak of the African classical swine fever epidemic in China, the state issued a series of requirements, and at the same time, it also provided a series of prevention and control programs for farmers. As long as we strictly implement the plan and pay more attention to some details, we can effectively avoid the occurrence of the epidemic.

If a nearby farm is found in daily life, when pigs of unknown causes are smuggled, they should timely report to the relevant departments while ensuring their own safety, so as to avoid further spread of the epidemic.

Even if there is an epidemic in the farm near their home, farmers do not have to worry too much. According to China's new prevention and control program, farmers within three kilometers of the epidemic farm can not be forced to be culled as long as the pigs are not infected. Unlike before, a farm gets sick, and all farmers within three kilometers are implicated.

If classical swine fever is found, it must be reported in time, and do a good job in treatment to ensure the safety of the farm.
